Definitions

  • This invention relates to a seat back position indicator.
  • the apparatus is particularly suited for passenger seats on conveyances such as passenger aircraft, where large numbers of people are seated in closely-spaced ranks and files, and must be observed by cabin staff at various times during the flight, such as during take-off, landing, in-flight emergencies and turbulent weather. Ordinarily, during these events the flight attendants must make a general announcement that seat backs and tray tables must be moved to a full upright and locked position. Then, the staff must circulate through the cabin to visually observe each seat back and determine that it has, in fact, been moved to the correct position. As aircraft have become larger and seat spacing more dense, it is correspondingly more difficult for the cabin staff to properly visually observe and verify that the seat backs are in the correct position.
  • seat backs that include a shell or other seat back component that remains in essentially the same position so that it does not encroach on the space of the aft-seated passenger.
  • the padded seat back itself is positioned forward of the shell and moves within the area forward of the shell. In these instances, it is very difficult or impossible to visually determine whether the seat back itself is upright, because the shell of the seat remains upright in the same position at all times and blocks direct visual observation of the seat, particularly from the sides and rear.
  • the seat back may rotate only slightly downwardly without significant rearward movement, making it difficult for the cabin staff to observe the seat back position in relation to the surrounding seat backs.
  • Prior art seat back indicators have included lights incorporated into the seat backs to provide an illuminated indication of seat back position.
  • Other seat designs incorporate sensors that transmit seat back and seat belt position status wirelessly to a cabin control panel or to a hand-held personal device used by the flight attendants. These designs are expensive, place further load on the aircraft electronics and power supplies, and are subject to abuse or damage from wear and tear. Thus, such designs may be more suitable in some aircraft environments than in others.
  • the invention disclosed in the application provides a relatively inexpensive, mechanically simple and reliable method of verifying passenger seat back position in a conveyance such as an aircraft.
  • a visual seat position indicator apparatus for providing an indication that a seat having a seat bottom, and a seat back movable between reclined and an upright position, is in either its upright or reclined position, including a visual indicator mounted for movement on a visually-exposed surface of an upper portion of the seat back; and a mechanical linkage acting between the visual indicator and the seat back for moving the indicator in response to movement of the seat back, the relationship of the indicator to the seat back providing a visual indication of the position of the seat back.
  • the indicator is a button mounted on the upper portion of the seat back.
  • the apparatus includes a bezel mounted on the upper portion of the seat back and surrounding the button, the position of the button in relation to the surrounding bezel providing the visual indication of the position of the seat back.
  • the linkage includes a pusher acting on the button to allow it to move as the seat back moves.
  • the seat back includes a stationary seat back shell assembly within which the seat back moves, and the indicator is mounted for movement on a visually-exposed surface of seat back shell assembly to provide a visual indication of the position of the seat back within the seat back shell assembly.
  • the seat back includes a stationary seat back shell assembly within which the seat back moves and a bezel mounted on an upper, visually-exposed surface of the seat back shell assembly.
  • a button is mounted for movement within the bezel; and a linkage allows the seat back and the button to move in relation to the bezel to provide a visual indication of the position of the seat back within the seat back shell assembly.
  • the linkage is adapted to allow the button to move downwardly into the bezel to expose adjacent interior walls of the bezel as the seat back is reclined, and the interior wall of the bezel has a surface condition that is visually distinct from the surface condition of the button, wherein when the button is withdrawn into the bezel, the interior walls of the bezel provide the visual indication that the seat back is in the reclined position.
  • the linkage includes a pusher acting on the button.
  • the surface condition of the interior wall of the bezel comprises a color and the surface condition of the button comprises a color that is visually distinct from the color of the interior wall of the bezel, wherein when the button is withdrawn into the bezel, the interior walls of the bezel provide the visual indication that the seat back is in the reclined position.
  • an aircraft passenger seat includes a base on which is positioned a seat bottom and a seat back movable between reclined and an upright position, and a visual seat back position indicator mounted for movement on a visually-exposed surface of an upper portion of the seat back.
  • a mechanical linkage acts on the visual indicator for moving the indicator in response to movement of the seat back, and the relationship of the position of the indicator to the seat back provides a visual indication of the position of the seat back.
  • the indicator is a button mounted on the upper portion of the seat back.
  • a bezel is mounted on the upper portion of the seat back and surrounding the button, the position of the button in relation to the surrounding bezel providing the visual indication of the position of the seat back.
  • the seat back includes a stationary seat back shell assembly within which the seat back moves, and the indicator is mounted for movement on a visually-exposed surface of seat back shell assembly to provide a visual indication of the position of the seat back within the seat back shell assembly.
  • the seat back includes a stationary seat back shell assembly within which the seat back moves, and a bezel mounted on an upper, visually-exposed surface of the seat back shell assembly.
  • a button is mounted for movement within the bezel, and a linkage acts on the button for moving the button in relation to the bezel to provide a visual indication of the position of the seat back within the seat back shell assembly.
  • the linkage is adapted to allow the button to move downwardly into the bezel to expose adjacent interior walls of the bezel as the seat back is reclined, and the interior wall of the bezel has a surface condition that is visually distinct from the surface condition of the button.
  • the interior walls of the bezel provide the visual indication that the seat back is in the reclined position.

  • FIG. 14 is a closer perspective view of the uppermost portion of the seat backs of the seats shown in FIG. 13 .
  • FIG. 1 shows an aircraft passenger seat 10 according to one embodiment of the invention.
  • Seat 10 includes a fore-and-aft translating seat bottom assembly 12 , and a seat back assembly 14 , including a stationary seat back shell assembly 16 within which the seat back assembly 14 moves.
  • a seat back rest 15 is shown in FIG. 13 .
  • a headrest assembly 18 is mounted for sliding movement in a headrest bracket 20 near the upper end of the seat back assembly 14 .
  • the seat bottom assembly 12 moves to initiate and achieve recline of the seat back assembly 14 .
  • the seat back assembly 14 also moves in a generally corresponding down-and-up vertical plane.
  • the seat 10 is removably attached to the deck of the aircraft by means of a base, not shown.
  • a linkage including a pusher 22 and a slide bar 24 , is attached to the seat back assembly 14 via a ringed, pull pin 26 , as is shown in FIG. 3 , or another suitable attachment such as a bolt and nut.
  • the seat bottom 12 assembly translates fore and aft as the seat position is varied by the seat occupant.
  • a seat back position indicator 30 is mounted on the seat back assembly, as shown in FIG. 4 , and provides a visual indication to the flight crew of the position of the seat back assembly within the stationary back shell assembly 16 .
  • the seat back position indicator 30 includes four components. As is best shown in FIG. 5 , two of the components, a bezel 32 and indicator collar 34 , snap together by means of ears 34 A, 34 B formed on opposing sides of the indicator collar 34 that fit into slots 32 A, 32 B in the bezel 32 . Note the assembled unit in FIG. 6 . The assembled bezel 32 and indicator collar 34 fit into a surround 36 .
  • the surround 36 has a pair of transversely-extending internal ridges 36 A, 36 B that cooperates with one of a plurality of transversely-spaced ribs 34 A, 34 B on the opposed outer surfaces of the indicator collar 34 .
  • This allows the bezel 32 to be spaced from the surround 36 , as shown in FIG. 8 .
  • the space allows for the thickness of plastic or leather seat coverings to fit between the bezel 32 and surround 36 .
  • a button 38 is fitted into the assembled bezel 32 , indicator collar 34 and surround 36 .
  • the button 38 includes a visible button top portion 38 A sized to fit within the indicator collar 34 , and two resilient side wings 38 B and 38 C that extend through side openings in the surround 36 .
  • the wings 38 B and 38 C come into contact with the surround 36 and flex downward. This causes the button 38 to be sprung down and aides in the retraction of the button 38 when the pusher 22 is drawn down, as when the seat back is in a reclined position.
  • the pusher 22 When in the take-off and landing position, the pusher 22 lifts the button 38 in the bezel 32 to a position generally flush with the top of the bezel 32 . This is shown in for example, FIG. 10 .
  • the button top portion 38 A and the surrounding seat back shell assembly 16 are preferably of the same or similar color, allowing the button top portion 38 A to be non-apparent to the passenger and observed by the cabin staff as indicating that the seat back assembly 14 is in the proper upright position.
  • the pusher 22 does not act to draw the button 38 downward. Rather, the pusher 22 draws itself out of the way of the button 38 , allowing the button 38 to move down on its own using the wings 38 B, 38 C as springs.
  • the button 38 would have to move a large distance during recline. With the disclosed design the seat back assembly 14 can move a great distance, but the button 38 only moves just enough to show the “not upright” color. This keeps the device small and lightweight.
  • the indicator collar 34 is preferably of a contrasting, readily observable color or pattern, and with the button 38 in the lower position the color or pattern of the inside wall of the indicator collar 34 is visible to the cabin staff and indicates that the seat is not in the upright position, as shown in FIGS. 9 and 10 .
  • the indicator 30 may be located in one of several locations on the seat back shell assembly 16 , but the illustrated location is considered preferable in that it is at the highest, most easily visible surface on the seat 10 when viewed from above as would be the case when being observed by a member of the cabin staff.
  • the bezel 32 would ordinarily not be visible by someone seated in the seat, or in a seat aft of the seat 10 , thus reducing the possibility of tampering or abuse by passengers.
  • the absence of a lighted indicator reduces cost of the initial installation and maintenance of the system, is less obtrusive and more in keeping with a desire to maintain a relaxed, comfortable environment within the aircraft cabin.
  • FIGS. 13 and 14 it is apparent that the seat back shell assemblies 16 of the three seats 10 are themselves at the same height in a fixed position.
  • the seat backrest 15 of the center seat 10 is in a lowered position. This would not be apparent to a passing flight attendant because of the position of the fixed seat back shell assembly 16 .
  • the flight attendant can easily see that the indicator collar 34 is visible, whereas the buttons 38 fill the bezels 32 on the two outboard seats 10 .
  • the seat position indicator may also have application in other types of seats, including seats with seat backs that have only slight rearward or vertical movement during seat adjustment.
  • the essential point is to provide a readily visible indicator to the cabin staff of the position of the seat back. It is considered advantageous to position the indicator in a location that is unobtrusive to the seated passengers, and that the indicator itself be unobtrusive and of significance only to the cabin staff.
  • the disclosed mechanism could be designed to work in reverse such that the button is colored and rises above the surface of the seat back to indicate a “not upright” configuration. This is considered to be inferior to the above disclosure of this application since it would be visibly unattractive and could more easily be broken.
